A sensor (100) for monitoring external loads acting on a pin assembly includes a pin (24) having an axial interior bore defined therein and having a length defined from a first end to an opposed second end thereof. A core pin is mounted axially within the interior bore of the pin spaced radially inwardly from the interior bore for relative displacement with respect to the pin. A capacitor (108) is provided having an inner capacitor plate (118) mounted to the core pin (106), and an outer capacitor plate (114) mounted to the pin (24), such that relative displacement of the core and the pin (24) due to external loading on the pin (24) results in relative displacement of the inner and outer capacitor plates (118,114). The capacitor (108) is configured and adapted to be connected to an electrical circuit (110) to produce signals indicative of external loading on the pin based on relative displacement of the inner and outer capacitor plates (118,114).
